             Summary: checknative command to probe for winutils.exe on windows
                 Key: HADOOP-11057
                 URL: https://issues.apache.org/jira/browse/HADOOP-11057
             Project: Hadoop Common
          Issue Type: Improvement
          Components: native
    Affects Versions: 2.5.0
            Reporter: Steve Loughran
            Priority: Minor


hadoop's {{checknative}} command looks for native binaries and returns an error 
code if one is missing.

But it doesn't check for {{winutils.exe}} on windows, which turns out to be 
essential for some operations. 

Adding this check to the -a (or default) operation would allow the check to be 
used as a health check on windows installations
